if initializaton of lcd means entry mode set, display on display off , clear display , all this , then i have done it .. will u plz explain once more . The problem is you've written your code as a "program" (like in software with delays). In vhdl you write a description of hardware (i.e. a text (...)
Hello, I am new to FPGAs and lcd devices. I am trying to interface an lcd device with a Spartan 3 kit (lcd module - 2 line-pre connected in it). Does anyone have a basic vhdl code to display a single character / word on the lcd panel. I am finding the codes available here and on the net (...)
how to initialize lcd in vhdl ! with the boring détails i searched about it ! but I didn't understand how it works
Hello friends Its the first time for me to deal with lcd, now I am trying to display some data on the lcd of the spartan 3e starter kit from xilinix.

working first time... i have to first display a word on lcd and then the word should roll on the lcd screen.. using altera de2 board/xilinx.. can anyone tell the vhdl code or the sequence of steps involved?
Hi, I am a second year electrical engineer student doing a project on multimeter. I have been trying to get the lcd display to display the mode the multimeter is in. I found a code online called lcd_Controller to initialize the lcd display. However, whenever I reset, the (...)
hi all.... i am interfacing an lcd with fpga. i want to convert the character to ascii so that i can display it using an lcd. i am storing the characters to be displayed in a string and using for loop i am retrieving it one by one. but i need to convert it to ascii. i am using vhdl. is there any inbuild (...)
Atleast give me a program for Binary to Hexadecimal conversion using vhdl..
Hi, I'm trying to display a word on the lcd (Spartan 3E vhdl) depends on the condition inputted by the user through switch. Sample if I press 011 on the switch, I will display the word BLINK, can anyone guide me on whats wrong with the code below. library IEEE; use IEEE.STD_LOGIC_1164.ALL; use (...)
dear all i have virtex 5 evaluation platform "ML505" which contains fpga connected with DVI controller "CH7301C so, i need to display image stored in block RAM on display "lcd'. i read the data sheet of CH7301 and some application notes but still i can not start to write vhdl code for it. as i known there is some data (...)

Dear its very helpful. Problem is that it is in vhdl can anyone translate in VERILOG.
hi all, i need for a project to decode characters sent to RS232 Receiver module the RS 232 receiver will feed its data to the lcd display and that will be on spartan 3A . i have the RS232 Receiver module done but what i am missing is the part related to the lcd display as i want one and i hope it is in (...)
Hi, for the past few days I've been playing around with a Spartan 3-AN Starter Kit Board. I'm interested in learning as much as I can, but now I'm stuck, and need a fresh pair of eyes to look over my code, and correct me where I made a mistake... I'm trying to initialize and write something to the 2x16 lcd display that comes on the board (S6A00
